The evolution of sunglasses or shades has a lot of interesting details.
Did you know that one of its earliest forms was made of emeralds? They were used by Roman Emperor Nero as mirrors during gladiator fights.
In the 12th century, the Chinese used smoky quartz to protect their eyes from glare. The same crystals were used in Chinese courts to conceal the judges' facial expressions while questioning the witnesses.
The Eskimos, however, were believed to be the first to use flattened ivory glasses as protection from the harmful reflected rays of the sun.
Over the following centuries, spectacles were created to serve different purposes—first, to correct specific visual impairments; second, to help people with syphilis because sensitivity to light was one of the symptoms.
In 1900s, it became very popular when Hollywood stars used it so fans and paparazzis wouldn't easily recognize them. In 1940s, it was marked as a fashion accessory.
Just like clothes and shows, fashion guidelines have been set in wearing shades:
1. The have to suit the shape of one's face. Judy Ann Santos, who has a round face, needs angular frames that have straight lines as opposed to soft edges. KC Concepcion, who has a long face, should also choose rectangular frames, while Marian Rivera, who has an oval face, can pretty much wear almost all kinds of shades.
2. They have to flatter your other facial features—like nose, forehead, cheekbones, and even ears. Those with wide forehead, for example, should consider colorful rims or frames to draw the attention to the eye area.
3. They have to be a perfect fit. The bridge and saddle should fit the nose well. The temple, or the legs that extend from the frame front to behind the ears, should also have the right length.
4. They should follow your style preference. Stick to a classic style if you want your shades to blend well with any environment or occasion. But if you're after being trendy, try out the shutter, or any pair in a bold or unique color or shape.
5. Lastly, make sure it's sun-proof. Check for sunglasses with a sticker that reads "Z80.3," which indicates that they meet the standards for UV protection established by the American National Standards Institute (ANSI); or anything that has the 0-4 rating (0 for insufficient UV protection, 1 for sufficient UV protection, 2 for good UV protection and 3 for full UV protection), adhering to European and Australian standards.
